About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X415SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 415 mm stroke tasks. The Ø25 bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel or aluminium minis in damp, food, or outdoor spots. Fixed TPU bumper pads decelerate the stroke-end impact without adding bulk.
The built-in magnet supports CMSG, DMSG, and EMSG switches for position sensing, while the CA rear pivot cover allows direct clevis mounting. For practical sizing, plan for about 147 N of real work at 0.5 MPa, which means it lifts roughly 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X415SCA Is Used
Diverter Gate Actuation
Pushes heavy cardboard cartons on a washdown packaging line using the 245.3 N thrust, with the stainless rod surviving daily moisture exposure.
Textile Loom Tensioning
Extends 415 mm to position tensioning rollers, using the CA pivot clevis to maintain alignment while tracking fabric weave.
Pallet Dispenser Separation
Cycles horizontally to feed empty pallets into a stacking zone, relying on the fixed TPU bumpers to absorb repetitive stroke-end shocks.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X415SCA the Right Cylinder?
If you need less force, the Ø20 bore provides 157.0 N of push at 0.5 MPa; stepping up to the Ø32 yields 402.2 N. This 415 mm stroke is well within the 500 mm maximum for the Ø25 bore, but at this length you must carefully manage side loading to prevent rod bending. The CA back cover suits pivoting articulations, and you can pair it with LB foot, FA flange, or TC trunnion hardware using the ISO 6432 mounting interface.
Because the standard MI relies on air pressure to move and hold, the piston will drift if air is lost or the valve is centred. The TPU bumpers only soften the end-of-stroke impact and act purely as decelerators, never as a brake. To suspend a load safely, fit an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI25~40 Stainless Steel Mini Cylinder MI25X415SCA FAQ
This Ø25 bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The CA back cover provides a rear pivot point for clevis mounting, and the body conforms to ISO 6432 dimensions for standard mini-cylinder brackets.
